To expose someone to incorrect answers on a test is to place fraudulent information in memory and then say to the brain, qDon't remember these answers.q It is for this reason the only answers you will encounter in this book are the correct ones. For those who wish to memorize only the answers, there are no formulas needed, no math, no electronics or theories to learn. This manual contains the answers to all possible questions in all tests from Technician Class, General Class and Extra Class license tests. In addition, the manual also provides the answers to the Volunteer Examiner's test. However, many people want to know why and many need a framework on which to relate the answers. That is why this book is arranged so that theories, formulas, rules, and regulations are explained in separate chapters. General theories and concepts of electronics and antenna design along with F.C.C. regulations are presented to the reader. Formulas, explanations, and diagrams from various sources give the reader all the information needed to pass the licensing tests, all in one book. This is a qtwo-prongedq approach. You chose the path that is best for you.This manual contains the answers to all possible questions in all tests from Technician Class, General Class and Extra Class license tests. In addition, the manual also provides the answers to the Volunteer Examinera#39;s test.
